The federal government has declared 42 counties disaster areas. Flooding has caused more than $1.5 billion in property damage in the Nashville area alone, city officials said.

Piles of debris stretched for blocks in the city's Bellevue neighborhood Sunday.

Soggy furniture, drywall and flooring lined the curbs as residents and volunteers tried to stay positive while cleaning up the damage flooding left behind.

"We have no choice but to solve this problem, and we're going to solve it with enthusiasm and try to have fun doing it. We have some hurdles to cross, but we've already gotten across quite a few," Nashville resident Russ Hazelton told CNN. "We'll see what the next few days bring."
